.BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 568,846, dated October6, 1896. Application filed August 20,1895. Serial No. 559,986. (Nomodel.)

I 0 aZZ whom it may concern:

Be it known that I, JACOB R. GRIFFITH, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Baling-Presses, of

which the following is a specification, reference being had therein tothe accompanying drawings.

My invention relates to improvements in hay-presses.

It relates more particularly to the class of hay-presses in which theexit end of the baling-chamber is contractible. It relates, further, tothe class of hay-presses in which a rebounding pitman, connected to afollower operatin g in the balin g-chamber, is reciprocated by means ofa double-armed lever revolved by suitable power, in combination with aspring tension operating upon the pitman.

The object of my invention is to provide a novel and efficient mechanismfor contracting or expanding the exit end of the baling-chamber; toprovide a simple and effective tucker connected with the baling-chamber,com prisin g an apron pivoted within the baling-chamher and a pivotedplatform mounted upon the baling-chamber and so connected with the saidapron as to depress the free end of the apron when the follower has beenwithdrawn for a charge to be placed in the baling-chamher; to provide anovel retaining mechanism combined with bracing for the baling-chamher;to provide an improved bed-plate having fixed guides for guiding thevibratory end of the pitman, together with means connected with thebed-plate for locking the pitman at the end of its stroke and means forchecking the rebound of the pitman after each compression, and toprovide certain new and improved features of construction and com Fig. 3represents a plan view of the bedplate and the forward end of thepitman, togetherwith the double-armed lever which operates the pitman.In this view the pitman is shown in its locked position with one of thearms of the operating-lever about to engage the cam on the pitman-head.In this view the normal position of the spring-actuated roller forchecking the rebound of the pitman is shown in dotted lines. Fig. trepresents a longitudinal vertical sectional view of the tucker and aportion of the balingchamber, In this view the position of the parts ofthe tucker during compression of the hay is shown in dotted lines. Thesolid lines represent the position of the parts after the follower hasbeen withdrawn. Fig. 5 represents a front elevation of the hay-presswith the remote parts removed for greater clearness. Fig. 6 representsan elevation view of the retaining mechanism, bracing mechanism,tool-box and tucker, and apertion of the baliiigcliamber. Fig. 7represents a vertical sectional view taken on the dotted line J y ofFig. 6, the right-hand side of the baling-chai'nber and tool-box beingbroken away. Fig. 8 represents a side eleva tion of the bed-plate, aportion being shown broken away, so as to show the construction of thecheckingmechanism. Fig.9 represents a plan view of one of the retaininglevers, the U -shaped bracing-rod and the side of the baling-chamberbeing shown in section. Fig. 10 represents a perspective view of theplate. Fig. 11 represents a rear view of the balingchamber and tensionmechanism, the extreme ends of the sides of the baling-chamher being cutaway. Fig. 12 represents a side elevation view of one of theretaininglevers. Fig. 13 represents a broken-away portion of the rightend-of the bed-plate -in elevation and section and the spring checkingmechanism in elevation. Fig. 14 represents a perspective view of theplate.

Similar letters and numerals of reference indicate similar partsthroughout the several views. v

A indicates the forward axle, B the rear axle, and O the wheels, uponwhich the press is supported.

D indicates the baling-chamber.

E indicates the pitman, to the rear end of which is secured a followeror head-block F.

G indicates a horizontal bed-plate connected at its rearend by means ofthe two tubes H, forming a reach to the forward end of thebilling-chamber.

. ends of which are secured to the sides of the balingchamber. Securedupon the front axle is a casting N, to which the forward end of thebase-plate G is pivotally connected and which serves as a fifth-wheelfor the press. A vertical shaft 0 has its lower end pivoted in thebed-plate and its upper end pivoted in the collar J.

To the upper end of the shaft 0 is secured a crosshead P, to one end ofwhich is secured the rear end of a tongue Q, and to the opposite end ofwhich is secured the rear cnd of a brace-rod 1-1, the forward end ofwhich is secured to the forward end of the tongue. Secured to the shaft0, between the arch l and the bed-plate G, is a horizontal doublearlnedlever S, the ends of which are provided with friction -rollers T,adapted when the shaft 0 is revolved to operate against a headblocksecured at the forward end of the pitman, as indicated by U.

V indicates a hopper upon the top of the baling-chamber, through whichthe hay is fed to the bailing-chamber.

1 indicates the upper and lower frames of the baling-chamber, consistingof an angleiron at each corner of the baling-ehamber. 2 and 3 indicate,respectively, the upper and lower plates of the baling'chamber. Theseplates are narrower than the inner width of the baling-chamber, so as toadmit of the rear end of the balingchamber being contracted by thetension mechanism.

Secured upon the upper side of the balingchamber to the rear of thehopper is a cast tool-box l, which is provided with a trans versepartition 5. To the rear side of the toolbox is pivoted a cover (3,which serves also as a platform for the man who is feeding thehating-chamber and as an operatinglever for depressing theapron 7, whichis an obliquelyinclined plate,the forward upper end of which is pivotedin the baling-chamber just below the forward edge of the tool-box. A lug8, upon the forward edge of the apron 7, is adaptedto strike against thelowerside of the tool-box and prevents the apron from dropping too lowat its rear end. A plate 9 is titted between the apron 7 and the cover(5, the upper and lower edges resting, respectively, in transversegrooves, one in the lower side of the cover and the other in the upperside of the apron. A slot extending transversely across the bottom ofthe tool-box permits movement therethrough of the plate 9 when thetucker is operated.

Each side of the tool-box at or near its forward end is provided with aprojection 10, which is provided with two vertical openings, throughwhich extend the two arms of a U- shaped strap 11, the lower end ofwhich embraces the rear axle and the two upper ends being provided withscrew-threads, to which are fitted the nuts 12. Between the lowerangle-irons l and the rear axle on each side of the baling-chaniber isacasting 13, which is provided with twovertical openings, through whichpass the arms of the strap or stirrup 11. Upon each side of thebalingchamber are located three retaining-levers 14, the rearinwardly-curved ends of which extend through openings 15 in the side ofthe baling-chamber. The retaining-levers 14 are disposed one above theother on each side of the baling-chamber, the upper lever being pivotedbetween a casting us, located below the projection 10 of the tool-box,and a casting 17, lo 'atcd below the lever let. The middle lever ispivoted between the casting l7 and a similar casting 18. The lower leveris pivoted between the casting lb and the casting 13. The upper andlower side of each retaining'lever is provided with a verticalprojection 19, cylindrical in form, which enters a vertical opening inthe adjacent casting. Each side of the castings 17, lo, and 18 isprovided with a vertical groove, (indicated by 20,) in which lie thearms of the strap 11.

The forward end of each of the retaining arms or levers 14- is providedwith a vertical disk, from the center of which inwardly extends acylindrical projection 21, upon which is mounted a coil-spring 22, theouter end of which rests against the disk-shaped end of theretaining-lever and the inner end against the side of thebaling-chamber. The tension of these coil-springs is such as to normallykeep the opposite end of the retaining-lever within the balii'ig-chamberand thus preventing the hay from expanding after compression. Each ofthe castings l7 and 18 is pro vided with a horizontaloutwardly-extending projection 23, the outer end of which isgroovedvertically. A vertical rod 24:, secured at its lower end to thecasting 13 and at its upper end to the projection 10, is bent outwardly,so as to lie in the grooves in the outer ends of the projections 23.

I will now describe the mechanism for contracting the exit end of thebaling-chambcr.

Referring to Figs. 1, 2, and ll, 25 indicates two horizontal plates, oneabove and one located below the baling-chamher and extendingtransversely across it. A vertical rod 26 has its upper and its lowerends pivoted in vertical openings in the castings 27 and 28, which aresecured, respectively, to the upper and the lower angle-irons 1 on oneside of the baling-clmmber. The plates 2-5 are secured one at each endof the vertical rod 26. The free ends of the plates 25 are pivotallyconnected to the ends, respectively, of a vertical bar 29, located uponthe side of the balingchamber opposite to the rod 26. Revoluble upon thebar 29, one below the upper plate 25 and the other above the lower plate25, are two friction-rollers 30.

Forward of the bar 29 and farther removed from the baling-chamber isavertical bar 31, the ends of which are pivoted in vertical openings oftwo brackets 32, which are secured to the side of the baling-chamber,one to the upper angle-iron 1 and one to the lower angle-iron. Eachbracket 32 is provided with a convex-faced cam at its outer edge, overwhich the roller 30 is adapted to travel when the plates are swung ontheir pivoted support. A horizontal rod 33 is secured at its rear end tothe bar 29 and passes from thence through a horizontal opening in anenlarged central part of the bar 31. The forward end of the rod 33 isscrew-threaded and has fitted to its screw-threaded end a hand-wheel 34.Mounted upon the rod 33, between the hand-wheel 34 and the bar31, is astiff coil-spring 35. By revolving the handwheel 34 in the properdirection the rollers are made to travel over the cam-surface of thebrackets 32, thus drawing the sides of the baling-charuber closertogether or forcing them apart, depending on whether the plates 25 aremoved forward or backward.

The following is a description of the guiding mechanism for thevibratory end of the pitman:

The head-block U is a cylindrical-formed casting provided with alongitudinal opening, into which the forward end of the pilnian ismovably fitted. To the under side of the head-block U is revolublysecured a frictionroller 36, adapted to travel between theguiding-flanges 37, 38, and 39 upon the upper face of the bed-plate G.Upon the left side of the head-block is a beveled cam 40, adapted toreceive the impact of the rollers T, upon the double-armed lever S, whenthe pitman is in the position shown in Fig. 3. To the extreme front endof the head-block U is vertically dovetailed thereto a hardened casting41, the front end of which is curved so as to be adapted to receive therollers T. The headblock U is held on the pitman by means of a rod 42,the forward end of which is secured to the head-block and the rear endof which passes around a horizontal plank 43, which lies against andparallel to the pitman, to the rearward portion of the pitman to whichit is secured.

The flange-guide 37 is located upon the right-hand side of the bed-plateG as viewed from the front of the machine, and is curved forwardly andto the right until a point near the front end of the bed-plate isreached, at which point it curves toward the left. The guiding-flange 38is located at the rear end of the bed-plate and lies parallel to theflangeguide 37. The flange-guide 39 is located at the forward end of thebed-plate and has a portion of its length parallel to the curved forwardend of the guide 37, and at its extreme forward end is provided with aconcaved front side adapted to receive and hold the roller 36 when thepitman is in the position illustrated in Fig. 3.

The forward end of the bed-plate on its under side is provided with asemicylindrical projection 44, which lies in a vertical plane that isobliquely inclined to the longitudinal center of the pitlnan when thepitrnan is in the rearward position, as shown in Figs. 1 and 2. Thesemicylindrical projection 44 is grooved for a portion of its lengthfrom the front end in order to permit the movement therein of aright-angled bar 45, the vertical leg of which is adapted to slide in aslot cut vertically through the bed-plate and joining the opening in theprojection 44. The said slot is indicated by 46.

To the vertical leg of the right-angled bar 45, at its upper end, ispivoted a horizontal roller 47, the under side of which moves along theupper side of the bed-plate. The springactuated roller 47 serves notonly as a buffer for the free end of the pitinan at the forward end ofits stroke, but also forces the roller 36 into the seat in the front endof the flange 39, and thus serves as a locking device for holding thefree end of the pitman in the said seat.

Secured within a longitudinal opening in the horizontal leg of the angle-bar is a horizontal rod 48, which extends rearwardly and to theright and passes through an opening, to which it is movably fitted inthe. rear end of the projection 44. At the rear end of the rod 48 issecured the forward end of a coilspring 49, the rear end of which issecured to a projection 50 on the underside ofv the bedplate G. Mountedupon the rod 48, to the rear of the projection 44, is a coil-spring 51,the rear end of which rests against a plate 52, secured upon the rod 48near its rear end. When the rod 48 is in the rear posit-ion, (shown inFig. 13,) the coitspring 51 does not bear upon the rear end of theprojection 44, and it does not operate until the roller is forcedforward by the striking against the roller 47 of the roller 36, that issecured to the under side of the head-block U. At such a time itrelieves the strain upon the relatively light spring 49 and prevents thepitman from moving too far forward, and, in connection with the spring49, forces the roller on the headblock U into the concaved front end ofthe guide 39. In order to assist the hay in forcing the pitman to itsforward position, a coilspring 53 has its forward end secured to a clip54, which is securedto the connectingrod K near its forward end, therear end of the said spring being secured to the plank 43.

My invention is operated as follows: The shaft 0 is made to revolve bymeans ofv power applied to the tongue Q, thus revolving the double-armedlever S, which in revolving forces the forward end of the pitman to theright through the intermediacy of the rollers T comingin contact withthe cam 40 on the head-block U at the front end of the pitman. After theroller 36 has passed to the right and out of the concaved front end oftheguide 39 the tension of the springs 49 and 51,'operating theangle-bar l5, forces the roller 47 rearwardly, and this in turn forcesthe pitman rearwardly by pushing against the roller 36 on the head-blockU. In the meantime the roller '1 runs along the inclined surface of thecam 4L0 and finally into the concaved front of the chilled casting -.tl,at which time the power of the lever S is applied against the pitman,forcing it rearwardly, the roller 36 following the guide-flange 37 andcausing the pitman to assume the position shown in Figs. 1 and 2. \Vhcnthe pitman has reached the limit of its backward movement, the roller '1is disengaged and the pitman springs forward, due both to the tension ofthe hay that was compressed during the rearward movement of the pitmanand to the tension of the spring 5-3. During the time that the pitmanand follower are in the forward position the man standing on theplatform 0 fills the forward part of the bailing-chamber with haythrough the hopper V. The rearward movement of the follower forces thehay backward into the rear portion of the baling-chamber, past theretaining-arms 14, which are forced outward at their inwardly-projectingends. As soon as the follower on the pitman recedes the retaining-leversllspring into the chamher and prevent the hay that has been compressedfrom springing past them. At the same time the weight of the man who isfeedin g and standing on the plat-form O, which was raised at its freeend, due to the hay pressing against the swinging apron 7, causes theraised end of the platform to lower, and through the intermediacy of theplate f) forein g the apron downward at its free end, and thus tuckingdown the hay under the apron that otherwise would give the bale a raggedappearance. In case it is desired to make the bales more solid, thehand-wheel is turned in a direction such as will force the rod forward,and thus drawing the rollers 30 forward up the inclined face of thebrackets and drawing the two sides of the chamber toward each otherthrough the intervention of the plates 25. The spring 35 is provided onthe'rod 33 in order to give a certain amount of elasticity to thecompressible end of the billing-chamber. After the roller '1 on thelever S has released the pitman it springs forward, the roller 36following the guide-flanges 37, 3S, and 39. At the forward end of thebed-plate the roller 36 strikes against the roller 47, which is forcedoutward against the tension of the spring 49 until thecompression-spring 51 comes in contact with the rear end of theprojection H, relieving the spring 49 and causing the pitn'ian-roller 36to slide into the coneavcd face of the guide 39, in which position itrests until the lever S, in revolving, brings one of the rollers T incontact with the cam -10, at which time the forward end of the pitman isforced to the right as viewed from the front, as hereinbefore described.

Various departures in construction maybe made from what I have describedwhile still remaining within the scope of my invention. For instance,the shaft 0, the lever S, and the cross-head P maybe cast in one piece,if found desirable. The conformation of the guides and the manner ofapplying them to the bed-plate may be varied to suit convenience orpleasure, and other modifications may be made without departing from thespirit of my invention.
